It is apparent that as many of the'devices may be installed as desired,and in such locations and With such lengths of depending wire hangerrods as may be estimated for the attachment thereto of suitable crossbars for they support of ceiling elements. It is also apparent that ourdevice provides convenient and flexible means of meeting emergenciesdisclosed in the requirements for ceiling construction ate-rthe-completion of the concrete floor, and also for solving incidentalproblems as .to hanging factors connected with the Y ceiling.

/ Particular attention is called to the freedom'conferred on our deviceby its structure from a usual and serious hazard common to ceilinghangers. The ordinary Wire hanger rodrprovided with a loop seatable on aform Whenv the rod is projected through the form, oi'lers ari-example.The loops often become displaced and Whenv the concrete is laid theloops 'are not securely embedded in the concrete to support Weight thatmay be attached tothe rod. The result is often the pulling of the hangeraway from the concrete flow in process of attaching the running bars, amore serious delayed result beingl the falling of the ceiling. Ourdevice assures an adequate support, since the bent plates cannot bedistorted appreciably by heavy pressure and are not subject to lateraldisturbance. v

. We may provide means of velevating the plates Jfrom the surface of thehorizontal membersof the form, and may install devices Valso atrotherlocations for embedment inthe beam members of the concrete floor.

We have described the hanger as used With Wooden joist molds. It isobvious thatV it in connection with steel joist ing ceilings under anyother type of reinforcedv concrete floor construction.

' Other variations .in use, and analogous modifications of orm,-Willappear as suitable to meet diferentconditions, which may be employedwithout departing from the spirit f and rgeneral disclosure of thisapplication.

What We `claim and desire to vsecure by LetterslPatent lis l. A ceilingsupporting member projectible having a head located above the formboard, and an anchoring member supported on the formboard and adapted jmember for supporting the head above and outV of contact with the boardto (permit embedment of the head in concreteipoured lontov the board.V

2. Aceiling supportingrod having a hook located: above a form board, andan anchoring member having an opening to receive the rod for supportingthe Vhook out ofcontact with thejboard .to permit embedmentof the hookin concrete poured vonto the board.

3. A ceiling supporting member projcctible through a form board having ahook located above the form board and an open ended lambdoid platesupported on the form board having an opening through Which the saidmember projects for supporting the hook out of contact with the formboard to permit embedment of the hook in concrete poured onto the formboard.

4. A ceiling supporting rod projectiblc through a form board having ahook located above the Jform board, and an inverted V shaped platesupported on the form board having an aperture in its apex through whichthe rod projects, for supporting the hook to permit embedment of thehook in the concrete poured onto the form board.
